Is it HAM or Ham? (#1348)

Steve, KE5SF, is wondering where the term "Ham Radio" comes from. Is it an acronym? How many of the old hams tales are true?

Baofeng 5R Mini the most tested handheld is it a Clean Radio?

Baofeng 5R Mini the most tested handheld is it a Clean Radio?

In this video I go through the functions of this new radio. I also test the radio for purity on the band and see if it can pass the FCC limits.
The Baofeng 5R Mini is a compact and affordable dual-band handheld radio designed for amateur radio enthusiasts and emergency communication. Despite its smaller size, it delivers reliable performance on both VHF and UHF bands, offering clear audio and decent transmission range. The simplified design makes it easy to operate, while still supporting common Baofeng accessories like external antennas and programming cables. Overall, the 5R Mini is a practical choice for beginners or those needing a lightweight, budget-friendly portable radio.

Your Attenuator is LYING to You. Here’s How to Prove It.

Post author By admin
Post date November 7, 2025

Your Attenuator is LYING to You. Here’s How to Prove It.

Everyone uses the NanoVNA to tune antennas and check SWR… but today we’re doing something way cooler. I’m using the NanoVNA-F V2 to X-ray an RF attenuator and find out whether it’s actually doing what the label claims — or whether I’ve been feeding fake values into my TinySA and destroying my test results.

🛠️ GEAR FEATURED:
👉 NanoVNA-F V2 (50kHz–3GHz): https://geni.us/hAZP
Take an additional 5% off from 11-5 to 11-30-25 with code RU9DM3TY
👉 20dB attenuators: https://geni.us/E7K7p3o
👉 40dB attenuators: https://geni.us/Pz4Bdf

📎 GET THE CHEAT SHEET:
The exact step-by-step bench workflow shown in this video is available as a printable PDF here: https://temporarilyoffline.com/blogs/tos-blog/stop-guessing-start-measuring

In this video you’ll learn:

✅ How to calibrate the NanoVNA for S21 attenuation measurements
✅ How to test fixed attenuators AND step attenuators
✅ How to tell good RF hardware from “Amazon special garbage”
✅ How many dB your attenuator really provides (not just what it says)
✅ How to protect your spectrum analyzer or SDR before you blow it up

If you ever test radios, amplifiers, filters, or harmonic suppression, this method will save you both money and gear.
